Specification of Letters Iatsnz.

Application filed February 7, 1912. Serial No. 676.628.

,Generators and Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention. sucj as will enable others skilled in the art to which it appertains to make and use the same.

' My invention relates to a combined gas generator and burner, and it particularly relates to a device of this character designed to be used in connection with a cooking stove of ordinary construction.

A11 object of the invention is to provide a device of this character which may be fitted into the firebox and seated upon the grate of stoves of diiierent sizes, or having different sized fireboxes, with equal ciliciency.

A further object to provide a device of this character lltUillg a bottomless air chamher on which the gas burners are located and from which, or through which they receive the necessary oxygen for combining .With the gas.

A still further object is to provid a bined fuel supply pipe and generator pipe and burner pipe, all in one piece. and thereby combining economy and efficiency in the construction thereof. I

A still further object is to provide a mixing chamber surrounding the gas jet and .w-,having an open side through which the justed, without removing flame may be inspected, and if necessary ador disarranging any of the parts.

A still further object. is to provide a valve for regulating the flow of liquid fuel through the pipes, and an indicator associated therewith for gauging the flow of fuel.

A still-further object is to provide a fuel supply tank communicating with the supply pipe and having a novel clasp or clanip ing device. therein for holding a piece of filtering material.

Otlum'pbjects and advantages will be hereinaftjer set forth and pointed out in the clainisr In the accom anying drawings which are made a part 0? this application, Figure 1 represents a stove with the burner appliedand having a section broken out through which the burner may be seen. Fig. 2 is a vertical. sectional view through the generating and burner piyes and. through one of the mixing chambers. Fig. 3 is a perspective detail view of one oi the mixing chambers removed. Fin. 1 is a detail plan view of the {range or imlicator. and, Fig. 5 is a 1 vertical sectional view taken centrally through the fuel supply tank and a section of the supply pipe,

llle'tcrrin r more particularly to the drawing in which similar reterence numerals designate corresponding parts throughout the several views, 6 indicates a stove of ordibars thereof. A bottomless air chamber 8 is seated upon. the grate bars and has the cover 9 formed with a trough 1t and'a tongue 11.. A pair of arcuate mixing chambers 12 are seated on the cover and secured thereto by any propermeans. The mixing chamliiers are aperturedat their base while the air chamber ham a corresponding aperture at two op iiosite edges, and in these apertures is seated the burner pipe 13. This burner pipe comprises one nuanberoi a combined fuel supply pipe and generator pipe and burner pipe, the supply pipe being designatial. 14 and the generator pipe 15. This combination' consists of a length of pipe bent over so as to constitute the two horizontal sections 13 and 15, while the fuel supply pipe cxtends through an aperture in the side of the stove (3 and communicates withtlze fuel sup ply tank 16, which may be supported in any convenient manner above the level of the burners.

I The generator pipe section lies directly over the burner pipe section, the latter having one or m re jet openings, 'as indicatml at. 17, which are disposed centrally within the lTliXlil i}; chambers. A cut-oil valve 1:; is located between the jets 17 so that one or both of the burners may be used, as desired. The cover 10 provided with openings 19 at each side of the tongue 1.1. and over these openings are located deflector plates 30 which are inclined in the direction of the mixing chambers. The mixing chambers are open at thcir top, also at the side next to the deflector plates.

Secured to the generator pipe 15, by any proper means such as, for instance. set screws 21, are the spreader-s E22, centrally located over the gas jets and adapted to sp ad the flame when the gas from said jets is .burning. The sides of the air chamber 8 latenicdOct. 15,131.73.

nary constructionand '7 indicates thegratemay be provided with yielding flanges 23,

which may be bent up or down, as desired ,in order to close the spaces between the exterior walls ofthe air chamber and the interior walls oi the store, or fire box, and

thereby direct the major part of the air,

passing through tliegrates, through the air chamber.

The deflector plates may be hinged onto theair chamber as at 241-, and may be provided'with astop which re'sts upon the end wall of the air chan'iber for holding the deflector in its normal position. When.

' however, it is desired to inspect, clean or repair the gas jets, the del'lector may be easily drawn away from the gas jetsand thereby provide ample. working room.

The oil tank 16 is pret'er.-ibl v provided with a strainer 16 and with the usual tightly fitted cover 16". The fuel supply pipe 14 communicates with said supply tank at a, point near the bottom thereof. and a piece of suitable filtering material 2V is placed over the aperture by which the tank and pipe comn'iunicate.

vide tonatwayshaving'the oil tlow t'reel through the pipe, it will. be necessary to renew the littering element quite often. I

I provide for ].lIlt'l-Zl and easily rene\ .'ing the littering element. by means ot'the meehanism shown in Fig. in which two aperturcd members it and 2d are hinged together at .39 and are provided with a spring clasp 10. I member which secured to the innerjwallot thesup-ptv tank and has its apertures in tea" istration with the outlet aperture of the tank. and by swinging the member 2S outhard. the littering,element- 26 may be ".quieldy placed and the member 98 maybe quickly snapped hack into the position shown.

in operation. liquid fuel passes fromthe supply .tanh through thesupply pipe, and the quantity thereof isregulated by the valve 15 and the gauge 1.5, and the oil eontinues its course thence and flows through the jets 17 and fills or partlyfills the priming trough 10, whereupon the supply is'cut ott bvineans ol the valve 15, and the fuel within the trough is ignited, thereby heating the pipe sections 13 and 15 to such an 'lhese elements constitute aelaspso long as fuel is admitted through the pipe.

Of course it is necessary to properly suppl v and mix oxygen with the gas, and this is provided for by the particular construction and relation of elements, in which the air passes upward between the grate bars,

through the air-chamber and through the openings 19 into the mixing-chamber, the deflectors '20 causing the air to pass into said chamber through the side opening thereof. l do not limit the invention to the exact details of constructionherein shown and deserit'ied, but the intention is limited only by a reasonable interpretation of the appended claims.

\Vhat I claim is t. in a gas generator. a combined oil supply pipe and gas generator pipe having a heat spreader thereon, a burner pipe having a jet opening therein, a. mixing chamber s ated between the first said pipe and the burner pipe and partially surrounding the jet opening. said mixing chamber being open at one side, and an inclined deflector located adjacent to the jet opening and opposite to the open side of the mixing chamber for ousing air to pass into said chamber through said open side.

:3. .In a gas generator, a combined oil supply pipe and gas generator pipe, a b rner pipe having; a jet op ui'ing, a bottomless air chamber on which the burner pipe is seated.

a mixing elannher having an open side and being seated upon the burner pipe and upon the air chamber. the first said pipe communieat ing with the burner pipe, said jet opening heing uithin the mixingqhamber and adapted to direct a llame'againstthe first said pipe. and a deflector hinged on the air chamber and being inclined upwardly toward the open side of. theimxmg chamber for directing the passage of air thereinto,

said deflector having .a stop for holding it in proper relation to the mixing chamber independently thereof. said deflector plate being adapted'to be swung away from the openv side of the mixing chamber for the purpose speeified.

Til-testimony whereof I have signed my name to this specificatlon 1n the presence of two subscribing witnesses.
